The best advice that I can give someone (because someone amazing once said it to me) is to not forget about your imperfections, but also not to obsess over them. What I mean by this is if you are not completely happy with something in your life, find a way to change it, without making it your absolutely only priority and becoming miserable if you don't achieve an amazing outcome on your first try.
Training our attention and awareness qualities is one of the best ways that I know of, to learn to get in touch with our discerning mind and the energy within our body. Such training is like holding up a mirror onto our own minds, just as we do with our faces, and instantly recognize what is it that needs fixing.
I don't think that you can be truly spiritual without being religious. It just doesn't work. A sociologist of religion named Nancy Ammerman has finished a new study of religion in everyday life. She concludes that the SBNR is a unicorn. By this she means that it is a species that does not exist in reality.
